How To Get Content Of A File ?

i am building some web page with template engine and i run on one problem: i want to import a content of some file and then use it in asp script so the solutions are this:

1: Create file system object and use ReadAll to read the content but there is a problem because it dosent render the importet file i get just the asp code

2: Create XML object and load the file into the xml but here is another problem this proccess takes quite a lot of time so it will be very slow for the web site especially that i want to import more the one file...

3: Create file system object and user ReadAll to read the content and then use eval(reasponseString) to execute this code... but i dont belive to much in this solution i dont know why but it seems to me it's not right.....
